The problem is the more time I'm on here the more ideas I get.
Leading evidence: 'more time i'm' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'more time i'm' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Adjust plenum position once the throttle body is re-attached' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I disconnected the MAF wiring from the MAF and housing.

I used a hand screw driver type socket and tightened as much as possible, I think you get a better feel for potential stripping that way.

This will allow you to adjust the plenum position once the throttle body is re-attached.

RSS who supplied the plenum also instructed me to hand thread the bolts through the throttle body and into the plenum before actuall install to check they didn't 'bottom out' before fully tightening.

I gave it a quick wipe with a clean damp cloth, also on the attaching surface to the plenum, just to make sure there was nothing to spoil the sealing o-ring.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Installed my IPD Plenum today. It replaces the stock plenum behind the throttle body. The new plenum is cast aluminium with improved airflow characteristics. You can see from the pictures how the airflow is directed rather than hitting the back of the stock plenum.
Here's my how to incase anyone else does this modification.
1) Remove air box to access throttle body. At first I just tried removing the hose but you really need the space so remove the entire unit. I disconnected the MAF wiring from the MAF and housing. I did not remove the MAF from the airbox.
2) Disconnect the plastic breather vent line (attached to the left side of the stock plenum) by squeezing the ribbed plastic clamp and pulling.
3) Remove the 5x10mm bolts that attach the throttle body to the stock plenum and surround. Once the throttle body is released I wrapped a clean cloth around it for protection and positioned it out of the way on the left hand side.
4) Undo the clamps on the rubber boots fully, you'll need alot of play here. The instructions mention to remove the check valve from the rubber boot on the left but I couldn't get it off so just proceeded carefully with it on. With the clamps undone as much as possible force the boots as far left and right as you can, this will take some muscle...
You'll have to twist and force a little to get the stock plenum out but it does come out eventually.
5) Here comes the tricky bit, getting the new plenum in between those rubber boots. I slid the LHS boot all the way on the LHS manifold (with both clamps) so that it was flush with the manifold and slid the RHS boot as far onto the manifold as I could. Take the RHS clamp off the boot closest to the open end and put it on the plenum side that will attach back at that point. Wiggle in the LHS of the plenum into the LHS boot whislt pushing the RHS against the RHS boot. Removing the clamp earlier allows the boot to compress more so you can force it more. The RHS boot has an internal ridge preventing it from sliding as far onto the intake manifold and if you put your hand inside the plenum and round to the right you can feel it. Use your hand in the plenum to help push the boot into position. You'll see it working, it just takes some force.
6) Once the plenum is situated within the boots position them so they are secure then tighten the clamps on either side furthest from the plenum. This will allow you to adjust the plenum position once the throttle body is re-attached.
(you can see the throttle body wrapped in a blue cloth in this pic)
7) Re-attach the breather vent line onto the spur on the plenum. Make sure the connecting cables to the throttle body go behind this when re-attaching as they did before.
8 ) Position the throttle body and re-attach with the 10mm bolts. I applied a little Loctite aswell. RSS who supplied the plenum also instructed me to hand thread the bolts through the throttle body and into the plenum before actuall install to check they didn't 'bottom out' before fully tightening. If it does you need to add a washer but mine was ok. There has been issues with stripping the bolts by over tightening. I used a hand screw driver type socket and tightened as much as possible, I think you get a better feel for potential stripping that way.
9) Once everything looks right and the throttle body is at the correct angle to re-attach to the air box then tighten the 2 clamps closest to the plenum on the rubber boots.
10) Re-attach the stock airbox and re-connect the MAF cable.
And there you go:
I have no idea about BHP or Torque increase at the moment but will dyno soon. It definetely feels like it 'pulls' better with quicker acceleration. I took her out for a hoon in the sun and had a smile from ear to ear. As a reward for all my tinkering I gave her a good Zymol wash and wax
Edited to attach pictures as embedded links no longer working. Pics in order of missing links, first 3 not added due to size and just showing a visual comparison between stock and RSS plenum
Thanks,
I gave it a quick wipe with a clean damp cloth, also on the attaching surface to the plenum, just to make sure there was nothing to spoil the sealing o-ring.
Oops, yeah, should have mentioned that. I did disconnect the battery and been on a good 40-50 mile drive since then...
It was part of a group buy on 6speedonline.com
$798 + $45 shipping a couple of months ago. Through
www.RPMNorth.com
I think they retail normally around the $900 mark.
I remember following this over on Rennlist. It would be very interesting to see what the gains are as they look pretty good.
Keep us up to date with your thoughts!
Within the next couple of weeks I'm going to get a dyno done then straight after another with the V-flow CAI fitted and GIAC remap. I'll post the results for all to see...
Great news, which dyno are you going to use?
Just make sure the remap is specifically for the combo you've got otherwise you might not get the results expected.
:thumbs:
I was going to use Regal Auto, they have a new Mustang dyno set up, if it's ready that is. They can also do the GIAC remap which has been developed in conjuction with the EVOM V-flow.
I'm waiting until I get my new mufflers fitted as they'll account for that too. Can't wait for them, right now it just doesn't sound 'right', the stock exhaust is way too feeble :twisted:
Haha, there's really not much more to do. The plenum was already bought, the Vflow is from my previous 996. The mufflers are part paid for and waiting to be fitted. It's just the remap left to buy. It's just so addictive
Then maybe a GT3 lip, upgrade brake fluid/ pads, cup steering wheel, Geo, etc etc... The problem is the more time I'm on here the more ideas I get. I blame you GT3 lot!
